I know the price will be a little cheaper in Sum Siu Po or in MK. WanChi is a little more expensive. Mainly because of their rent on HK island. You can get all the same stuff. Actually the no name brand, that you build from parts, are not that bad either. We bought some of the computers in the MK location for the office. It's been working fine for over 2 years already. It only cost us about 500
